non-moral expert, but as
a person frequently irritable, ungenerous and forgetful, and
intermittently and in small but definite ways bad. One thing I claim, I
have got my beliefs and theories out of my life and not fitted them to
its circumstances. As often as not I have learnt good by the method of
difference; by the taste of the alternative. I tell this faith I hold as
I hold it and I sketch out the principles by which I am generally trying
to direct my life at the present time, because it interests me to do so
and I think it may interest a certain number of similarly constituted
people. I am not teaching. How far I succeed or fail in that private and
personal attempt to behave well, has nothing to do with the matter of
this book. That is another story, a reserved and private affair. I offer
simply intellectual experiences and ideas.

It will be necessary to take up the most abstract of these questions of
belief first, the metaphysical questions. It may be that to many readers
the opening sections may seem the driest and least attractive. But I
would ask them to begin at the beginning and read straight on, because
much that follows this metaphysical book cannot be appreciated at its
proper value without a grasp of these preliminaries.

BOOK THE FIRST. -- METAPHYSICS.

1.1. THE NECESSITY FOR METAPHYSICS.

As a preliminary to that experiment in mutual confession from which this
book arose, I found it necessary to consider and state certain truths
about the nature of knowledge, about the meaning of truth and the value
of words, that is to say I found I had to begin by being metaphysical.
In writing out these notes now I think it is well that I should state
just how important I think this metaphysical prelude is.

There is a popular prejudice against metaphysics as something at once
difficult and fruitless, as an idle system of enquiries remote from any
human interest. I suppose this odd misconception arose from the vulgar
pretensions of the learned, from their appeal to ancient names and
their quotations in unfamiliar tongues, and from the easy fall into
technicality of men struggling to be explicit where a high degree of
explicitness is impossible. But it needs erudition and accumulated
and alien literature to make metaphysics obscure, and some of the most
fruitful and able metaphysical discussion in the world was conducted by
a number of unhampered men in small Greek cities, who knew no language
but th
